Abstract
A dynamic model was proposed for a honeycomb paperboard cushioning packaging system with critical component. Then the coupled equations of the system were solved by the variational iteration method, from which the conditions for inner-resonance were obtained, which should be avoided in the cushioning packaging design.
Highlights
Honeycomb paperboard is widely applicated in packaging industry due to its excellent performance in energy absorption and vibration attenuation
The oscillation in the honeycomb paperboard packaging system is of inherent nonlinearity [4, 5], and it should be treated as a double-degree-of-freedom system when the critical component should be considered [6]
These conditions should be avoided during the cushioning packaging design procedure
Summary
Honeycomb paperboard is widely applicated in packaging industry due to its excellent performance in energy absorption and vibration attenuation. The dynamic behaviors of honeycomb paperboard under dynamical compression and impact loading are studied thoroughly. The oscillation in the honeycomb paperboard packaging system is of inherent nonlinearity [4, 5], and it should be treated as a double-degree-of-freedom system when the critical component should be considered [6].
